AUTONOMOUS SURFACE VEHICLES (ASVs) carry out pre-programmed missions and can be monitored much more reliably due to their ability to constantly receive and transmit information via satellite.
BUOY is an umbrella term that covers all floats, whether they are stationary or able to move vertically and/or horizontally.

DRIFTERS float on the surface and are moved horizontally by ocean waves and currents.
PROFILING FLOATS adjust their buoyancy to move vertically through the water column;
STATIONARY FLOATS remain in one location.
MOORINGS are similar to stationary floats but are anchored to the seabed; large ones can act as a platform for researchers and equipment.
